6. ENGINE OIL LEVEL

Check the oil level daily with the engine stopped.
If the engine has just been stopped and is warm,
wait at least 10 minutes to allow the oil to drain
back to the oil pan before checking. Wipe the
dipstick clean then check oil level.
should always be within the safe range on the
dipstick (Fig. 11). Add the proper grade of oil to
maintain the correct level on the dipstick. All
diesel engines are designed to consume some
oil, so a periodic addition of oil is normal.
Warning:
Touching a hot engine can cause
serious burns.
Caution:
Do not overfill. Oil may be blown out
through the crankcase breather if the crankcase
is overfilled.
Caution:
Clean end of tube before removing
the dipstick to prevent oil contamination.

Caution:
If the oil level is constantly above
normal and excess lube oil has not been added
to the crankcase, consult with an authorized
Detroit Diesel service outlet for the cause. Fuel
or coolant dilution of lube oil can result in serious
engine damage.
The vehicle is provided with an oil reserve tank
in the engine. To adjust oil level, open the oil
reserve tank valve and allow oil to discharge into
the engine until the "Full" mark on the dipstick is
reached then close the valve. Check oil reserve
tank level and pour oil in the reserve tank if
necessary (Fig. 12).

7. ENGINE OIL AND FILTER CHANGE

Both the oil and filter should be changed every
12,500 miles (20,000-km) or once a year,
whichever comes first. However, changes that
are more frequent may be required when the
engine is subject to high levels of contamination
and/or overheating. Change intervals may be
decreased
experience on specific lubricants until the most
practical service condition has been established.
Always refer to the lubricant manufacturer's
recommendations (analysis of drained oil can be

helpful).
Caution:
engine oil when draining. Dilution of fresh oil can
occur which may be detrimental to the engine.
Change engine oil with the vehicle on a flat and
level surface and with the parking brake applied.
It is best to drain the oil when the engine is still
warm.
1. From under the vehicle, remove the engine
drain plug on the oil pan. Allow oil to drain
(Fig. 13).
Warning

and gloves to protect hands.
2. Reinstall the drain plug.
